History Services NSW records that two convicts, James Halliwell (per Camden 1831) and Daniel Torpy (Per Eliza 1832) "suffocated in a silo on Cockatoo Island on 4 October 1852".
Conditions in the penal settlement on Cockatoo Island were notoriously overcrowded and it was the subject of regular enquiries into the state of prisoner accommodation and the administration. The settlement was finally closed in 1869 when the convicts were transferred to Darlinghurst Goal.

The prison buildings have been currently nominated for World Heritage listing along with other convict sites around Australia. Archaeological digs are in progress and have revealed important evidence from Cockatoo Island's convict past.
